CHANGELOG.md

5.1.2

added

• ECPair and bip32 objects now have a lowR boolean attribute defaulted to false. You may set it to true to ensure that the sign method uses low R values (#1442) (This is to enable low R usage in Psbt, since we decided not to give the low R flag to the Psbt class, since it makes more sense to be an attribute of the Signer interface)

changed

• Name inconsistencies for Psbt class. (Quick fix)

5.1.0

added

• A new Psbt class for creating, distributing, combining, signing, and compiling Transactions (#1425)

changed

• TransactionBuilder: Migrate to stricter type checks during sign by switching to a single object parameter (#1416)

removed

• Block.prototype.checkMerkleRoot was removed, please use checkTxRoots (0426c66)

changed

• ECPair.prototype.sign now returns a 64-byte signature Buffer, not an ECSignature object (#1084)
• ECPair (and all ECDSA code) now uses tiny-secp256k1, which uses the libsecp256k1 library (#1070)

2.1.0

From this release users should use the HDNode directly (compared to accessing .keyPair) when performing ECDSA operations such as sign or verify. Ideally you shoud not have to directly access HDNode internals for general usage, as it can often be confusing and error prone.

added

• ECPair.prototype.getNetwork
• HDNode.prototype.getNetwork, wraps the underyling keyPair's getNetwork method
• HDNode.prototype.getPublicKeyBuffer, wraps the underyling keyPair's getPublicKeyBuffer method
• HDNode.prototype.sign, wraps the underlying keyPair's sign method
• HDNode.prototype.verify, wraps the underlying keyPair's verify method

2.0.0

In this release we have strived to simplify the API, using native types wherevever possible to encourage cross-compatibility with other open source community modules.

The ecdsa module has been removed in lieu of using a new ECDSA module (for performance and safety reasons) during the 2.x.y major release. Several other cumbersome modules have been removed, with their new independent modules recommended for usage instead for greater modularity in your projects.

---

Backward incompatible changes:

added

• export address, for address based utility functions, most compatible, just without Address instantiation, see #401, #444
• export script, for script based utility functions, mostly compatible, just without Script instantiation, see #438, #444
• export ECPair, a merged replacement for ECKey/ECPubKey, invalid types will throw via typeforce

changed

• address.toOutputScript, ECPair.prototype.fromWIF and HDNode.prototype.fromBase58 no longer automatically detect the network, networks.bitcoin is always assumed unless given.

• assert was used for type checking, now replaced by typeforce

• BIP66 compliant strict DER signature validation was added to ECSignature.fromDER, changing the exact exception messages slightly, see #448.

• new HDNode(d/Q, chainCode, network) -> new HDNode(keyPair, chainCode), now uses ECPair

• HDNode.prototype.toBase58(false) -> HDNode.prototype.neutered().toBase58() for exporting an extended public key

• HDNode.prototype.toBase58(true) -> HDNode.prototype.toBase58() for exporting an extended private key

• Transaction.prototype.hashForSignature(prevOutScript, inIndex, hashType) -> Transaction.prototype.hashForSignature(inIndex, prevOutScript, hashType)

• Transaction.prototype.addInput(hash, ...): hash could be a string, Transaction or Buffer -> hash can now only be a Buffer.

• Transaction.prototype.addOutput(scriptPubKey, ...): scriptPubKey could be a string, Address or a Buffer -> scriptPubKey can now only be a Buffer.

• TransactionBuilder API unchanged.
